Question

[2•(2x+8)]•16=15
x•(1+2+3+...100)=101•100
x la puterea a2a +16=2+4+6+...+32
(2x+1)la puterea a2a=(x-3)la puterea a2a

x+2supra x=3 supra x+1

Answer 1

(4x+16)x16=15
64x+256=15
64x=-241
x=3.7/3.(7)

3x=(x+2)(x+1)
3x=x^2+3x+2
x^2=-2
x=radical din -2 si nu scrie - sub radical , NU E POSIBIL!
